` A ( a, 0) , B( -a, 0) ` are two points. The equation to the locus of P such that ` PA + PB = c ` is

A

`4 ( c ^ 2 - 4a ^ 2 ) x ^ 2 + 4 c ^ 2 y^ 2 = c ^2 ( c ^ 2 - 4a ^ 2 ) `

B

` 4 ( c ^ 2 + 4a ^ 2 ) x ^ 2 - 4 c ^ 2 y ^ 2 = c ^ 2 ( c ^ 2 + 4a ^ 2 ) `

C

` 2 ( c ^ 2 + 2a ^ 2 ) x ^ 2 + 2c ^ 2 y ^ 2 = c ^ 2 ( c ^ 2 + 4a ^ 2 ) `

D

` 2 (c ^ 2 - 4a ^ 2 ) x ^ 2 - 4c ^ 2 y ^ 2 = c ^ 2 ( c ^ 2 - 4a ^ 2 ) `
